Biodiversity is the variety of life on earth. It covers different species of plants, birds, animals, insects and soils. It provides the basis for a number of goods and services – often called ecosystem services – that society, business and economies depend on.

Ecosystem services

Around 60 per cent of the world’s ecosystem services are being degraded or used unsustainably, which has a huge environmental and financial impact. The collective cost to the global economy of mismanaging our natural environment is estimated at $6.6trillion per year. At current rates this figure is estimated to increase to $28 trillion by 2050.

Our approach

We recognise that some of our projects have the potential to create a negative impact on local biodiversity. However, there are opportunities for us to leave a positive legacy by enhancing biodiversity as a result of our operations.


We are working to gain a deeper understanding of how our operations impact on biodiversity and aim to identify what measures we can take to reduce and mitigate their effects.

Excellent environmental management ensures that work is planned around any protected species on and near our sites. Many of our projects are proactively working to create a net gain in biodiversity.

Through our charity partner Groundwork, and other local charities, our employees have contributed to enhancing biodiversity in the local communities in which we work through our ‘lend a hand’ volunteer programme.

Natural capital

We are one of 50 businesses to support the development on the Natural Capital Protocol, a standardised framework to measure and value direct and indirect impacts and dependencies on nature.

The Construction Industry Research and Information Association BIG Biodiversity Challenge encourages construction projects to ‘do one thing’ for biodiversity. Since the challenge started in 2014, more than 20 of our projects have taken part. These include:
